i need to remove my steering stem to change clipons. i am have one problem though.

i lossen the pinch bolts to the forks i took the cap off of the middle bolt but the bolt will not loosen.

i have tryed a wrench that was in the tools with the bike and a peice of metal over it to get a little more leverage. it managed to dig in to the bolt a little but not lossened.

how the heck do you loosen this thing. any advice? thanks

 

I use a proper socket and breaker bar the steering stem nut has about 75 ft/lbs of torque so a wrench isnt going to cut it
